Definitions

  • the invention relates to a ner driving to control biological processes, in particular digestion processes in water, with the further features of the preamble of claim 1.
  • WO 01/88205 AI a process for the production of sugar or sugar-containing products from sugar-containing vegetable raw materials is known, which is carried out at least partially in the presence of added natural food-compatible resins.
  • These food compatible resins can be tree resins, especially rosin or rosin derivatives. These tree resins are used to inhibit special microorganisms.
  • Chemical means are known to avoid the uncontrolled growth of microorganisms, but they are associated with considerable negative side effects. Such chemical substances are usually also toxic to humans and animals. Therefore, natural substances are preferred that have the required antimicrobial properties.
  • the present invention is based on the object of providing a method for controlling biological processes in water which is environmentally friendly, compatible with humans, simple to carry out and inexpensive.
  • Tree resins can control the growth of microorganisms and / or macroorganisms in water.
  • control includes the inhibition of growth, the destruction and the removal of microorganisms and / or macroorganisms.
  • the biological processes are controlled by means of the tree resins in a purely natural way.
  • Tree resins are also easy to store and can be stored in without problems
  • the method according to the invention can be used in a wide variety of areas, for example in the food industry, for example in brewery pasteurization; air purification systems; in the oil industry; fountains; water ears, water tanks, waste water systems, Wastewater treatment etc.
  • Rosin and / or rosin derivatives can be used with particular advantage as tree resins. It is precisely these resins that have proven themselves in the process for controlling biological processes in water and have proven to be particularly advantageous.
  • the tree resins in particular rosin and / or rosin derivatives, are added to the water in an amount of approximately 0.01 mg / 1 to 10000 mg / 1, preferably 0.1 mg / 1 up to 1000 mg / 1, in particular 1 to 100 mg / 1 added.
  • the tree resins can be used as saline solutions or suspensions, preferably as potassium salt solution, in particular as 0.5 to 35% potassium salt solution or as sodium salt solution, in particular as 0.5 to 35% sodium salt solution.
  • the tree resins can also be used as other 5 to 20% saline solutions or suspensions can be added.
  • the tree resins prefferably be added as an alcoholic solution or suspension, preferably as a 1 to 25%, in particular as a 10 to 80%, ethanol solution.
  • the tree resins or their saline or alcoholic solutions or suspensions can be stabilized before they are added to the water.
  • they can be mixed with at least one stabilizing agent, in particular with a surfactant.
  • a stabilizer prevents or prevents precipitation or flocculation of the tree resins before they are added to the water.
  • the stabilizer also aids in the distribution of the active ingredients once added to the water.
  • the stabilization rank is particularly advantageous in the case of longer storage of large amounts of tree resins or rosin and / or rosin derivatives in order to always ensure the same control properties of the biological processes in water.
  • the stabilizing agent can be selected from the group consisting of dioctyl sodium sulfosuccinate, sodium monomethymaphthalene sulfonate and dimethylnaphthalene sulfonate, N-lauroylsarcosine sodium salt, alkyl polyglycoside and
  • biocide it is also particularly advantageous to add at least one biocide to the water in an effective amount.
  • It can be z. B. act food-compatible, antimicrobial agents (z. B. hops or hop derivatives).
  • the biocides also include agents that prevent the growth or emergence of macroorganisms such. B. prevent mussels or the like.
  • the biocide can be selected from a group comprising ⁇ 5-chloro-2-methyl-4-isothiazolin-3-one, 2-methyl-4-isothiazolin-3-one, glutaraldehyde, 2,2-dibromo-3-nitrilopropionamide, 2 -Brom-2-nitropropan-l, 3-diol, 1-bromo-1 - (bromomethyl) - 1, 3-propanedicarbonitrile, tetrachloroisophthalonitrile,

  • the biocide In order to ensure an effective effect of the biocide, it can be added to the water in an amount of 0.01 to 10000 mg / l, preferably 0.05 to 50 mg / 1, in particular 0.1 to 10 mg / 1.
  • the proportion of tree resins can be approximately 0.1% to 99%, and in the opposite way the proportion of biocides can also be approximately 0.1% to 99%.
  • the tree resins or the stabilized tree resins can be added to the water in dry or pasty or viscous form.
  • the state of matter can also depend on the stabilizing agent or the saline or alcoholic solutions or suspensions, or can thus be deliberately influenced.
  • the tree resins or stabilized tree resins can expediently be added to the water at a temperature of -5 ° C. to 95 ° C. Within this temperature range it is also possible that organisms can grow if there is no control of the biological processes.
  • the tree resins or stabilized tree resins can be used in combination with hops or hop derivatives, which are distinguished by their antimicrobial properties.
  • Hop acid in particular beta acid
  • a mixture of resin acids, in particular tree resin acids and beta acids, which are added to the water in particular in a 50:50 ratio, leads to the control of biological processes, in particular the inhibition of growth, the destruction and also the removal of microorganisms and / or macroorganisms is optimized.
  • C E, a concentration (mg / 1) of chlorophyll a, which was analyzed in the extracted solution.
  • C E, b concentration (mg / 1) of chlorophyll b that was analyzed in the extracted solution.
  • Table 1 shows the amount and type of chlorophyll contained in the cultures of Chlorella vulgaris after their treatment with different concentrations of resin and beta acids after an incubation period of nine days. The results show that 100 ppm of the resin acids significantly reduced the chlorophyll content of a sample, which is a clear indication of an algae-inhibiting activity.
  • Bacillus stearothermophilus DSM 22 and DSM 457 were grown on a culture medium at 55 ° C. which contained known concentrations of resin acids. The percentage growth of the bacteria was measured in comparison to a control substance without any resin acids.
  • Independent patent claim 23 shows the advantageous use of tree resins in the control of biological processes in water, in particular digestion processes in standing or flowing water systems.
  • compositions for controlling biological processes in water are described in independent claims 24 and 27.
  • the composition contains a certain amount of tree resins. Rosin and / or rosin derivatives can be provided as tree resins. Further possible characteristics of the composition result from the method described above.
  • the composition contains a certain amount of stabilized tree resins.
